16 Feb 2018TL;DR: Six perspectives of fit are identified, each implying distinct theoretical meanings and requiring the use of specific analytical schemes, and explicit links between theoretical propositions and operational tests are argued for.
Abstract: This article develops a conceptual framework and identifies six perspectives of fit—fit as moderation, fit as mediation, fit as matching, fit as gestalts, fit as profile deviation, and fit as covariation—each implying distinct theoretical meanings and requiring the use of specific analytical schemes. These six perspectives highlight the isomorphic nature of the correspondence between a particular concept and its subsequent testing scheme(s), but it appears that researchers have used these perspectives interchangeably, often invoking one perspective in the theoretical discussion while employing another in the empirical research. Because such research practices weaken the critical link between theory development and theory testing, this article argues for explicit links between theoretical propositions and operational tests.

TL;DR: In this article, the authors identify a comprehensive inventory of consumers' hedonic shopping motivations based on exploratory qualitative and quantitative studies and develop a six-factor scale that consists of adventure, gratification, role, value, social, and idea shopping motivations.

TL;DR: The present report demonstrates the existence of a marked sexual difference in the volume of an intensely staining cellular component of the medial preoptic nucleus (MPON) of the rat and shows a possible morphological basis for the sexual differentiation of brain function.

TL;DR: A 13-item Revised Self-Monitoring scale is presented which measures only sensitivity to the expressive behavior of others and ability to modify self-presentation, and a 20-item Concern for Appropriateness scale is described which measures 2 variables that are directly associated with social anxiety.
Abstract: Snyder's (1974) Self-Monitoring Scale exhibits a stable factor structure that does not correspond to the five-component theoretical structure he presents. Sets of face-valid items that better approximate the theoretical structure are described. Correlations between these sets of items and measures of other constructs reveal that four of the five components are positively related to social anxiety. Effective social interaction is supposedly the high self-monitor's forte, and social anxiety appears to be incompatible with this. The correlational results therefore question the entire theory and indicate the need for a narrower definition of the construct. Adopting such a definition from Snyder's review article (1979), we present a 13-item Revised Self-Monitoring scale which measures only sensitivity to the expressive behavior of others and ability to modify self-presentation. A 20-item Concern for Appropriateness scale is also described. This scale measures 2 variables that are directly associated with social anxiety--cross-situational variability and attention to social comparison information. Both scales have acceptable internal consistency, and both yield 2 subscale scores as well as a total score. Prospective users of either scale are advised to treat the 3 scores separately.

TL;DR: In this paper, the authors proposed that these inconsistencies can be resolved by integrating agency and stewardship perspectives on duality, using data from 192 firms in 12 industries, and found that both the direction and magnitude of the duality-performance relationship vary systematically across Dess and Beard's environmental dimensions.
Abstract: Several studies have addressed the CEO duality-performance relationship, with inconsistent results. This paper proposes that these inconsistencies can be resolved by integrating agency and stewardship perspectives on duality. Using data from 192 firms in 12 industries, both the direction and magnitude of the duality-performance relationship was found to vary systematically across Dess and Beard's (1984) environmental dimensions. These results provide partial support for both agency and stewardship perspectives.
